Application September 16, 1948, Serial No. 49,521

This invention relates to improvements in a liquid vibrating apparatus and particularly to such a mechanism for producing cavitation of a liquid.

An object of this invention is to provide a with materials and members which may bel manufactured at reasonable cost, may be easily assembled and which will be eiiicient in operation with minimum wear to the parts.

The best embodiment of the invention has been chosen for illustrative purposes, but this embodiment should be viewed as being illustrative only and not as limiting because obviously the invention is capable of other embodiments having revised details of construction, so long as they fall within the ambit of the appended claims.

The invention itself, however, both as to its organization and its method of operation, will best be understood from the following description oi a speciiic embodiment when read in connection with the accompanying drawing, in which:

Fig. 1 is a partial side view and section of the vibrator.

Fig. 2 is a sectional elevation taken approximately along the line 2 2 of Fig. 1 and looking in the direction indicated by the arrows.

Fig. 3 is a sectional view taken along line 3 3 of Fig. 1 and looking in the direction indicated by the arrows.

Fig. 4 is a partial side elevation of a modified form.

Fig. 5 is a similar view showing another modi- Iication.

Referring in detail to the parts, II designates a motor suspended in a liquid container by means of a bracketed arm I2 secured to the motor casing and formed with a hooked upper end I3 adapted to engage over the rim of a tub or liquid container shown in Fig. l, by dot-dash lines I4. The dot-dash line I5 indicates the approximate liquid level.

2 Claims. (Cl. 259-1) Attached to and extending from the motor II are bracket arms IS which support a drum like housing I 6. The said housing comprises inner `and outer drum head members Il and I8 respectively which are joined by a circular wall member I9 which is formed with flanges 29 and 2|. Gaskets 22 and 23 are disposed between the drum head members Il' and I8 and the flanges 29 and 2l respectively. Bolts 24, engage through the outer ends of the bracket arms i6, the drum head member I'i, gasket 22 and flange 29 to support and secure the said parts together. Similar bolts 25 engage through the flange 2I, gasket 23, drum head member i8 and brackets 26 and secure said parts together. The said brackets 25 are secured at their outer ends 2l to acage 28 which encircles the vibrator mechanism and is designed as aguard to keep the operating mechanism of the vibrator free of any clothes or obstacles which may be contained in the tub or clothes container.

The said cage 28 may be disconnected from its inner section 29 which is in turn attached to the motor II by means of laterally projecting arms 3U and screws 3l. Screws 32 at a joint 33 and the bolts 25 engaging said brackets 2G are removed to disconnect the outer portion of the cage 28.

A motor shaft Se extends from the motor li through a packing 35 upon the drum head member I1 to a bearing 39 in the drum head member I8. Secured upon the said shaft 3A, by means of a pin 31, there is a rotor element 38, the outer periphery of which is serrated as at 39 and is formed with annular flanges 49 and 4I having serratures 42 and 43 upon their respective edges. At intervals along the periphery of the said circular wall member i9, there are radially aligned Vanes a@ which extend through the said circular wall member IS and are integrally formed therewith. The inner edges L15 of the said vanes IM are adapted to engage the serra tures 39 upon the outer periphery of the said rotor element 3B, during the revolution of the rotor.

The said serratures :i2 and 43 formed upon the annular ilanges 4G and 4I respectively are adapted to engage the inner ends l5 and l of vanes i8 and I9 respectively when the said rotor 38 revolves.

A conductor cable 50 with regulation plug 5l and switch 52 passes through a conduit 53 which leads along the bracket or suspending arm l2 to the motor I I and affords a means for conducting electric current to the motor.

In use, the apparatus is suspended over the edge of a tub or container (Fig. 1) and submerged in liquid within the container. When the current is turned on, the motor will rotate at high speed to give rotation to the rotor 38 whereupon the serratures 39 upon the periphery of same will successively contact and release the edges 45 of the vanes 44 causing rapid vibrations to the circular wall I9 and said vanes 44.

Similarly, the laterally extending vanes 48 and 49 will vibrate by contact with the serratures 42 and 43 respectively and transmit their vibrations to the liquid. The vibrations thus imparted to the said circular wall and vanes will produce cavitation of the liquid within which the apparatus is submerged. When the liquid is saponied and fabrics to be cleansed are also submerged in the liquid the cavitation of the liquid produced by the vibrations will create vacuums about the fabrics and create a cleansing effect thereon.

A modified form shown in Fig. 4 provides the vanes 44 upon the circular` wall only omitting the laterally projecting vanes 46 and 41 which extend through the said drum heads H and i8 as shown in Figs. 1 and 2. Fig. 5 shows a modified form 'wherein the vanes 44 are omitted and the varies 46 and 4'! are included. Other means besides the forms shown may be provided to set up a vibratory motion to produce cavitation of the liquid and the apparatus may be applied wherever cavitation of a liquid is desired.

A cage of square form is shown in Figs. 1 and 3. The outer periphery of the cage, however, may be of circular formation as indicated diagramatically by dot-'dash line 54 in Fig. 2.

I claim:

l. Ari apparatus for producing cavitation in a cleansing liquid within a container, comprising a suspending frame adapted to be partially submerged in said cleansing liquid, a motor upon said suspending frame, a drum secured upon the casing of said motor and adapted to be submerged in said cleansing liquid, the shaft of said motor extending into said drum, vanes extending outwardly and inwardly through the peripheral Wall of said drum, a rotor member having a serrated peripheral edge secured to the said extended motor shaft within the said drum and adapted, when rotated, to engage the inner edges of said peripheral varies, annular flanges extending from the said rotor member and having ser'- rated outer edges, laterally disposed varies upon the said drum extending inwardly and outwardly therefrom and engaging the serrated edges of said annular flanges upon the rotor when said rotor rotates, and means for conducting a source of electrical energy to the said motor.

2. An apparatus for producing cavitation in a cleansing liquid Within a container as defined in claim 1 including a two-part protecting cage, one part being secured to the casing of said motor and the second part being removably attached to the rst mentioned part.
